Target entity: PSR B1620−26
Context triple: [Messier 4, hasNotableObject, PSR B1620−26]
  • A. PSR B0531+21
    PSR B0531+21 is the highly magnetized, rapidly rotating neutron star at the center of the Crab Nebula, serving as one of the most studied pulsars in astrophysics.
  • B. Cygnus X-2
    Cygnus X-2 is a bright low-mass X-ray binary system in the constellation Cygnus, consisting of a neutron star accreting matter from a companion star and serving as an important source for studying X-ray emission and compact objects.
  • C. Scorpius X-1
    Scorpius X-1 is a bright low-mass X-ray binary system and one of the strongest persistent X-ray sources in the sky, located in the constellation Scorpius.
  • D. Cygnus X-1
    Cygnus X-1 is one of the strongest known X-ray sources in the sky and the first widely accepted stellar-mass black hole candidate, located in the constellation Cygnus.
  • E. Holmberg II X-1
    Holmberg II X-1 is an ultraluminous X-ray source in the dwarf galaxy Holmberg II, believed to be powered by accretion onto a compact object such as a black hole.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
